You might have noticed that there's a function to 'switch stadiums' in the PESEDIT Selector included in this patch. At the moment there are only 2 options available to choose from (Moses Mabhida Stadium, Durban & Schüco Arena, Bielefeld), but both are fantastic quality and worth their download. As the size of quality stadiums is quite massive, we decided to keep the optional which means clicking their buttons in the selector without downloading the additional package will result in an error message due to missing files.

Just copy the folder 'pesedit-stadiums' to 'kitserver' inside your PES 2011 main folder, so the structure is like:
'PES 2011/kitserver/pesedit-stadiums
